Keep current car or purchase new one?
I currently have a 2012 Mazda 3 with 163k miles on it. it needs new front struts, exhaust fixed, and my engine light just came on, i got the code pulled (P0171) from autozone and they said its most likely the O2 Sensor. I was quoted 2000+ to get it fixed. i have put in 2000 within the last 4 months into it for a new battery,alternator, front & rear sway bars, rear brakes and rotors. ive have the car for 10 years with no car payment. i feel something is starting to break or needs replacing every 3-6 months. is it worth it to keep the car and get those things replaced/ fixed, or should i look at getting something newer with less miles? if i get something new itd be under 20K. i also wont get much for my car because its a salvage title and has hail damage + starting to rust. let me know your thoughts.
